Comparison of weight status among two cohorts of US Air Force recruits

USAF cohorts were less likely to be overweight than corresponding BRFSS samples. There were 19.1 and 20.2 percentage point differences between overall crude rates of overweight/obesity between AF1996 and BRFSS 1996 and AF2000 and BRFSS 2000, respectively. Nevertheless, overall rates of overweight and obesity are increasing among young recruits in the USAF at a fairly marked rate (approximately one percentage point per year).
